SV650 ECU Decoder Part 5: They’re here!

The boards look really good. I’m waiting on some parts to show up from Mouser, but was able to mostly populate the board with all the parts. The nylon standoff under the LED display really provides a lot of strength and stability, only issue being that it’s just a millimeter or so too long, but nothing that my grinder can’t easily fix.

Really looking forward to testing on Saturday in the shop and then hopefully on Monday for my first track day of the season at Thunderhill!

Update: The board works great! We’ve even had a few situations where the error codes from the unit has helped debug problems with the bike. Right now my only complaint is that the green LED I selected for the neutral light has a very narrow viewing angle and hence is hard to see, especially during the day. Other then that, it works great!

On the regulator, you should remove the masking under the large metal back plate, this way it solders down to the copper pour under it and that copper can be used as a heatsink to prevent the regulator from overheating

On more recent generation boards using the LM7805 I did exactly that but it still ran too hot. Later I ended up switching to the Murata OKI-78SR switching power regulator which does not have a tab to solder to, but runs much cooler.
